Answer:
D. all real numbers
Step-by-step explanation:
4(x+3)-7greater than or equal to x+3(x+1)
4x+12-7> or equal to x+3x+3
4x+5>or equal to 4x+3
so, by testing
if x=1, is it true that 4x+5 is greater than or equal to 4x+3
4(1)+5=4(1)+3
9=7
hence it true 9 is greater than 7
Option D is collect
Answer:
Step-by-step explanation:
4(x+3) - 7 ≥ x + 3(x + 1)
4x + 12 -7 ≥ x + 3x + 3
5≥3
so this answer tells us that this equation will always be true no matter what number you plug in for x ... so all real numbers works

(1/10 (x)) fewer than the sum of 1/5 (y) and 2x so
1/10 (x)=1/10 times x=x/10
1/5 (y)=y/5
-x/10+y/5+2x
simplified it is
19x/10+y/5
